This movie shows the April 7, 1997 solar eruption
occurring, as observed by the LASCO coronagraph. The circle shown in the
center of the image outlines the sun, where it has been shielded. By
blocking out the sun in this manner, we are more able to observe activity
which is less bright in the solar atmosphere. In this case, we see a large
eruption of material, first coming from the lower left corner, and then
finally emerging in all directions.
